Key ON = Ignition Switch

Relay? ... If you mean Starter Kill Relay:

You would locate your Starter wire ( Usually at Ignition Switch )

Cut in Half

Cut half that goes to Starter goes to one side of Relay

Other cut half that goes to Ignition goes to other side of Relay

1997, i have a few manuals, all the other things i installed it using some manuals, and old alarm wires. but cant figure the starter kill relay option.

i was thinking abt install another alarm that come with engine starter but looks very complicated for the first time, so i choice this model of alarm without that option.. btw.. is not an simple one :D

im really bery happy with my instalation (will looks better after i hide all the wires), i have all the wires trough the seats :D

well hope you understand my english

Thanks

Locate the wire in the ignition switch harness (bundle of heavier gauge wires coming off the key) that shows 12V only during cranking, this is ur starter wire...

Set ur relay like this:

85 - starter kill/ground when armed wire from alarm

87A - Motor side of cut starter wire

(Jump a wire from 30 to 86)

86 - Key side of cut starter wire

1N4001 Diode across coil (85 and 86) Band side of diode facing 86.

No, when the key is "on" the starter wire will not show 12V, only ign wires will...it's like this:

Constant wires show 12v all the time

Ign wires show 12V when key is on and during cranking

Acc wires show 12V only when key is in acc position

Starer wires show 12V only during cranking

So when u turn the key all the way forward and the car begins to crank, the wire that shows you 12V only during this time, is starter.

well, tellme if everything is ok...

"Key On" Show me 12V everytime.

"Starter wire" only show 12V when the car are cranking, its the wire that i need to use for the Starter Kill Relay

Right?
